Patent CA-2167025-A1 (CA)
Inventor: GRIFFIN DANIEL WAYNE
IPC: G10L25/90
Filed: 1996-01-11
Abstract: A method of encoding speech by analyzing a digitized speech signal to determine excitation parameters for the digitized speech signal is disclosed.      The method includes dividing the digitized speech signal into at least two frequency bands, determining a first preliminary excitation parameter by performing a nonlinear operation on at least one of the frequency band signals to produce a modified frequency band signal and determining the first preliminary excitation parameter using the modified frequency band signal, determining a second preliminary excitation parameter using a method different from the first method, and using the first and second preliminary excitation parameters to determine an excitation parameter for the digitized speech signal.      The method is useful in encoding speech. Speech synthesized using the parameters estimated based on the invention generates high quality speech at various bit rates useful for applications such as satellite voice communication.

The joint includes first and second complementary, interlockable faces on the first and second members, respectively, and a respective plurality of mating teeth on each of the faces.  Each tooth has a peak edge extending substantially radially from the center point, and each pair of adjacent teeth defines a valley edge extending substantially radially from the center point between the adjacent teeth.  The first and second faces are oppositely disposed at the joint and are adapted for substantially mating contact with one another.  The joint also includes a screw for adjusting the distance along the axis between the oppositely disposed first and second complementary, interlockable faces on the first and second members for removably interlocking the first and second members into one of a plurality of angular orientations relative to one another.  The joint couples handles or other fittings to a pair of gripper jaw portions to facilitate gripping a polishing stone or other tool.          The joint also couples a tool head to a handle to define a more general modular tool.

Title: Alteration of sequence of a target molecule
Inventor: SULLENGER BRUCE A
IPC: C12N15/00
Filed: 1994-11-09
Abstract: Method for splicing a target nucleic acid molecule with a separate nucleic acid molecule. Such splicing gen-erally causes production of a chimeric protein with ad-vantageous features over that protein naturally produced from the target nucleic acid prior to splicing. The method includes contacting the target nucleic acid molecule with a catalytic nucleic acid molecule including the separate nucleic acid molecule. Such contacting is performed un-der conditions in which at least a portion of the separate nucleic acid molecule is spliced with at least a portion of the target nucleic acid molecule to form a chimeric nu-cleic acid molecule. In this method, the catalytic nucleic molecule is chosen so that it is not naturally associated with the separate nucleic acid molecule.

IPC: G06T7/00
Filed: 1994-11-29
Abstract: A method and system for automated detection and classification of masses in mammograms. This method and system include the performance of iterative, multi-level gray level thresholding (202), followed by lesion extraction (203) and feature extraction techniques (205) for classifying true masses from false-postive masses and malignant masses from benign masses. The method and system provide improvements in the detection of masses including multi-gray-level thresholding (202) of the processed images to increase sensitivity and accurate region growing and feature analysis to increase specificity. Novel improvements in the classification of masses include a cumulative edge gradient orientation histogram analysis relative to the radial angle of the pixels in question; i.e either around the margin of the mass or within or around the mass in question. The classification of the mass leads to a likelihood malignancy.

Abstract: A private base station location register supports the registering of multiple mobile stations at a private base station and provides control information for enabling a personalized call delivery feature at the private base station for each registered mobile station. When registration of a mobile station with a private base station is performed, the private base station location register receives mobile station information from a private base station along with assignment of a local unique address for each one of the multiple mobile stations registering with the private base station. When the private base station receives an incoming call for a particular one of the mobile stations, this local unique address associated with the particular station is provided by the base station location register as part of the incoming call information also received by the base station thereby allowing the base station to distinctively alert the particular mobile station. By receiving a local unique address for each of the mobile stations from the base station location register, the private base station is also able to advantageously offer various intelligent features which are personalized according to customer needs. For example, a calling party may have his or her name displayed on the reached mobile station for the convenience of the user at this mobile station.

Title: Method and apparatus for reducing adverse effects of optical beat interference in optical communication systems
Inventor: BODEEP GEORGE E
IPC: H04B10/18
Filed: 1996-12-16
Abstract: A method and apparatus for reducing noise in optical communication systems, wherein the frequency of light output from a signal laser is modulated or dithered to broaden the optical spectrum of the signal laser.  The broadening allows error-free data transmission within signal bands, despite the presence of optical beat interference.  Different dithering tones are emitted by each laser in the network.  The dithering tone for each signal laser in an optical network is chosen so that distortion resulting from the dithering tone falls outside the signal bands.

Title: Three-dimensional human cell cultures on cardiac valve frameworks and their uses
Inventor: PURCHIO ANTHONY F
IPC: A61F2/06
Filed: 1995-09-08
Abstract: The present invention relates to a method of growing a variety of different cells and tissues in three-dimensional cultures in vitro using human fibroblasts in the culture medium. In accordance with the invention, stromal cells, including but not limited to human dermal and cardiac fibroblasts, are inoculated and grown on a three-dimensional scaffold or framework. The human fibroblasts secrete human matrix proteins to supplement and replace the existing porcine matrix composed of decellularized heart valves or aortic walls and leaflets formed into three-dimensional constructs having interstitial spaces bridged by the stromal cells. The living stromal tissue so formed provides the support, growth factors, and regulatory factors necessary to sustain long-term viability and proliferation of cells in culture and/or cultures implanted in vivo. When grown in this three-dimensional system, the proliferating cells mature and segregate properly to form components of tissues analogous to counterparts in vivo.
